Abstract
The method of operating an image device comprises receiving an input of virtual tissues modeled with an arbitrary shape and a quantitative feature, simulating a TOF change or a signal strength change of ultrasound data having penetrated the virtual tissues modeled with a speed-of-sound distribution or an attenuation coefficient distribution in a first and in a second direction, and creating an image pair representing the TOF change or the signal strength change, creating a speed-of-sound distribution image or an attenuation coefficient distribution image of each of the virtual tissues as a ground truth of an image pair created in the corresponding virtual tissue, and training a first neural network that reconstruct the speed-of-sound distribution image from an input image pair or training a second neural network that reconstructs the attenuation coefficient distribution image from the input image pair.
